Again, you are confusing product categories with product/market fit.
Then you're not properly explaining the difference. Personally, after a point it is a distinction without difference.
I'd point out that additional models are only needed if current models are hopelessly unfit for some segment of the life cycle.
There's a lot more that can sink a model than just that. Just being "ugly" can do it. Plus, competition is generally good, which means that you'll have 3-4 companies all competing for the same market segment (more or less), which tends to give customers better options at lower prices.
My point is that the current notion of acquiring new land and contracting new charger station have various flaws. That converting existing pumps at gas stations to chargers is like a far wiser move.
Well, of course, but it has its own benefits as well. You see, the existing pumps are part of the existing paradigm, and "most" gas stations aren't necessarily going to be all that supportive of it, at least for now.
For example, installing Tesla chargers might help the direct owner of a Shell Station franchise, but it isn't going to help Shell.
The complexities of this, combined with things like possibly needing serious power refits to supply the electricity necessary for charging, meant that at least initially, while Tesla was building its charging network to help it sell more cars, greenfield development was generally faster and easier.
I expect otherwise. I think people in EVs will behave pretty much like people in ICEs. That they won't think about refueling/recharging until they are low. And when that warning light alert pops up, the locations identified by our century old Darwinian process of locating gas stations will provide a convenient spot.
I think that you're failing to account for new technology. Certainly, there will be those types out there, but the early adopters (who I will agree isn't going to be a 100% match for later adopters) are showing that most are perfectly willing to plug in most nights.
Even then, charging rates with a home charger are decent enough that if the driver notices they're at 20% - and the car should be warning them about that, they plug in overnight, and within 10 hours the car is at 80% or so, without the need to visit a faster charger and sit there waiting.
For longer trips, the software already takes the route into account and will plan the charging stops for you.
On restaurants - Yes, I kind of figure on them being for guests, used as an attraction for more customers.
Government involvement. Gov't offers money to acquire land and build charging stations. So people do that, it doesn't matter if it makes sense. Gov't is paying for it. Gov't didn't consider ongoing maintenance, it wasn't part of the deal, there is no gov't support. So the developers have little incentive to do so. They got their gov't money and are gone
Fair enough.
On gas stations - it might be better to rename them convenience stores, because that's actually how most of them make most of their money, gas is just a draw. that's why I figure that convenience stores will start shifting towards business models that assume a bit longer of a stop. Less "stop and go" and more "come in for a few!". IE rather than grabbing hot dogs off those roller things, you can get a burger or sub sandwich made to order. More seating. Etc...
Thing to remember is that gas stations actually close and open on a regular basis, as businesses. There's a lot of obviously ex-stations in my area. The newer places tend to have much bigger store parts attached, and yes, some of them have chargers. But I see the chargers closer to the highway than in the middle of the residential area of town.
I can certainly see this happening. in a bankruptcy, contracts can be violated and rewritten by the courts. Generally speaking, warranty and continuing service stuff are considered liabilities, little different than non-secured loans like credit card debt.
If the device owners are not on the ball, they can easily find themselves on the bottom of the debt pile to get anything at all, like continuing service or warranty work in a bankruptcy court.
Now, rewriting the firmware to *remove* offline functionality to force users into subscription models is, I believe, mostly untested in courts, though it might be illegal under EU law. Should certainly be illegal in my opinion.
Companies probably don't do it as standard because the expected class action lawsuit would cost more than the expected profit, even if they win.
Definitely not, Anker makes solid stuff.
Cell phones and Smart phones went through the exact same process. Multiple market segments, all with users of means, risk tolerance, concerns, circumstances, etc. As described in the Technology Adoption Life Cycle and Diffusion of Innovations links you have.. For example first gen 1 iPhone was very much early adopter only.
Gen 1 iPhone was a single model, the equivalent would be the Tesla Model S, or maybe even the Tesla Roadster.
Tesla currently offers the S, X, Y, 3, and Cybertruck. Because Musk has a gradeschooler's humor. That's 5 model lines.
Ford Mach-E
Chevy Bolt and EUV
Rivian R1T and R1S
Lucid Air
Volkswagen ID.4 and ID.Buzz
Hyundai Ioniq 5
Kia EV6
BMW i4 and iX.
The above looks like a pretty good number even for cellphone models.
I'm not going to say that more models wouldn't be good, that we aren't in a pause because early adopter types have mostly been satisfied while the "main market" types haven't been convinced yet.
What criticism of a current gas station based charger do you have that does not also apply to a brand new charging station based charger on newly acquired land?
The idea that gas stations to chargers would be a 1:1 fit as opposed to something like "quite a few gas stations are good spots for EV charging as well, but not all"
IE gas stations would definitely be a spot to examine for EV charging, but they aren't going to be universally good, because there are differences between EV charging and gasoline refueling.
Chargers are not install and forget, even is solar based.
Not something I ever argued. Matter of fact, "check use" should imply that one is very much NOT forgetting about them, and keeping track of use.
I still don't quite understand how we managed to install so many chargers that break at the slightest excuse. Tesla builds dependable chargers, EU has apparently been installing dependable chargers, what's up here?
You are making assumptions about means, risk tolerance, concerns, circumstances, etc that will result in many of these people not acting like early adopters of EVs. The product market fit that works for early adopters does not work for the main market. EVs need multiple product market fits for different market segments. This is what makes introducing a new technology so difficult, and take so long.
Cell phones and Smart phones actually spread pretty dang quick.
And we have a number of EV "product market fits". We have everything from the Nissan Leaf to the Cybertruck, for example. Do we need even more models? Probably.
But I'd argue that a single "Tesla Diner" is more a market test than a serious effort to spread the concept. Also, that just replacing gas station pumps with EV chargers also doesn't acknowledge the very real differences between charging vs refueling.
You're probably going to want more dwell time for charging.
I tend to generate a generic priority list for charging:
1. Home
2. Work
3. Convenient spot they already spend some time at
4. Inconvenient spot that they can at least find something else to do.
5. Inconvenient spot that they can't find something else to do in.
Worst case, businesses can always put in a couple EV chargers and check use. With solar power, there's actually arguments for increased daytime charging, so put in enough for employees + some percentage of customers. Check to see how often customers are using them. If it goes over some usage level, install more.
One can also figure that the chargers will have a lifetime - build enough to satisfy demand during that lifetime, maybe, figuring on assessing expansion options when time to replace the overall system comes up.
Slightly over half the population live in SFD and can thus be assumed to be able to charge at home. Even then, charging options at both apartments and work centers is expanding.
That a "build it and they will come sort of wishfulness". Its guesswork.
I'd argue that it isn't any more guesswork than building a new McDonalds or Chick-fil-a. Wawa is a known successful model. Heck, the one closest to me also has a line of Tesla chargers.
Restaurants may not be the spur of the moment decision you are hoping for.
Doesn't need to be "spur of the moment". People get hungry, want food. Many older people also want out of the car for a while. Combining those two with the third - get the car charged back up, is effectively getting paid three times.
And yes, a few chargers at pretty much anyplace people park for a bit is a good idea.
Just consider the "expected stay duration"
Motels expect ~8 hours. So they're good with level-2 charging, but you're going to want enough to cover at least the percentage of the clients you expect to be in EVs.
Movie theaters ~2 hours. A low end level-3 DC charger is good here. Only issue is that you can expect them to show up in batches.
Sit down restaurants ~1 hour - basic superchargers.
Fast food - 30 minutes - modern superchargers
Convenience store - 5-15 minutes: The highest power superchargers.
Or even just a Wawa. They have the ability to do burgers and subs, even vegan options. Plenty of drinks and snackfood available. Fresh fruit even.
Question is, do they really have to be? We all know ISPs oversell their backhaul, for example. That gigabit connection won't be a gigabit if everybody in the area is trying to download at full speed at the same time.
Same deal with charging EVs, I think. Put more chargers in, preferably capable of full speed individually, but what are the odds that you'd get 80 cars in during the exact same 15 minutes? That every single one of them would be properly preconditioned for a full speed charge?
If you have a few cars that have been there for 10-15 minutes already, their charging rate slows down naturally, the station can coordinate with the cars and driver's plans to ensure that the power is divided up in a equitable fashion.
As for the solar panels over the parking - I know it's not going to make a huge dent in providing all the necessary energy for charging the cars, but putting a structure over the top to shield them from the sun and rain is still very nice, at which point they might as well be solar panels.
A station that has 80 charging spots but normally only sees 3 of them being used at a time might still be able to satisfy most of their demand via the solar panels.
I have to agree with thegarbz - I think it is highly unlikely for a supercharger station to experience perfectly steady demand. At this point Tesla should have plenty of multiple yearlong examples to figure out likely usage patterns.
I'd expect, given food establishment (but no breakfast?) to see peaks around lunch and dinner periods: 11 am to 2 pm, 5 pm to 8 pm. A trickle of cars otherwise. Add good breakfast, add a peak at 6 am to 9 am. (8am would be when the retirees mostly show up).
All we really need to do is take existing gas stations and slowly convert gas pumps to charging stations, in proportion to the local market's transition to EVs. Today? Maybe convert one pump at stations with 12 pumps.
True Genius would take it a step or two past that. For example, it is a rare exception for somebody to be able to fuel an ICE at home, mostly restricted to a few farmers. But "most" EV owners can easily do so.
This means that the optimal recharging locations and optimal refueling stations are actually somewhat different. Especially if you go from ~5 minutes attended fueling to ~15 minutes unattended charging.
The latter gives businesses a much better opportunity to sell EV owners more stuff when they stop by for charging. It's why I figure that the "quick stop" gas stations with a microscopic building for smokes and drinks wouldn't be as popular as the expanded food options available at expanded gas stations like Wawa. Note: Not endorsing, just giving as an example.
Of course, I'm not going to give Elon/Tesla any "Genius" points for implementing something I was suggesting years ago. Back when a fullish charge was closer to an hour than 15 minutes, I felt that placing EV chargers next to restaurants made very good sense. Even today, while 15 minute charges are a bit fast for a sit down place, more suited for fast food or even a convenience store, the ability to either charge more fully or slowly to help conserve the battery might be good.
It binds more strongly than O2 or CO2, but not permanently. Just time removed from the source will clear it. Providing supplemental O2 will speed that up while supporting life functions if they got a larger dose.
Basically, CO will win most fights with O2 for hemoglobin, but when it is experiencing a few hundred per trip through the lungs...
The article gives us a vague description:
"The dedicated card and payment crime unit of the City of London police launched an investigation after receiving information from the intelligence firm WMC Global about the fraudulent kits being sold online."
How did they even know the guy was in London?
From Crown Prosecution Service:
"The investigation uncovered a large amount of digital evidence, which the prosecution used to build a strong case and successfully link Holman to the online offending."
And also:
“I hope this case sends a clear message to those intent on committing fraud: no matter how sophisticated your methods, you cannot hide behind online anonymity or encrypted platforms. Fraudsters like Holman will be robustly pursued by law enforcement, prosecuted by the CPS, and brought to justice.”
How did he initially get on their radar? Did Telegram provide authorities with whatever IP he logged in from, or maybe he just posted his email? Did he not really try to stay anonymous out of some belief that he wasn't doing anything illegal?
It could have also been a million dollar ransomware attack.
Regular use or only exception weirdness? If this covers a free battery for every device eventually, that would definitely provide some value that is pretty reliable (most Apple devices would benefit from a battery swap between two and four years in).
But if it only covers "battery fails", some rare event, then whatever.
